Yes it starts on Thursday, part of the Tour's quest to not be like the Ryder Cup (well, and get another TV day). As for previews, Steve Keating of Reuters has the pairings. The Mickelson-DiMarco v. O'Hern-Clark match looks like it could be good one, though everyone will be watching Woods-Couples v. Scott-Goosen. Meanwhile, Golf World's Brett Avery previews the teams. And Doug Ferguson offers notes following Wednesday's practice round and press conference.
As for the to-autograph-or-not-to-autograph spat, no one asked the Captains to clarify as far as I can tell. Instead lots of dreary questions asking for comparisons between the Presidents Cup and the Ryder Cup and other boring stuff. By having the players do joint press conferences, it turns into one big rally killer session.
